battery pack may create a risk of fire when used with
another battery pack.
• Use the jacket only with specifically designated battery
packs. Use of any other battery packs may create a
risk of injury and fire.
• Before using battery cartridge, read all instructions and
cautionary markings on (1) battery charger, (2) battery,
and (3) product using battery.
• Do not disassemble battery cartridge.
• If operating time has become excessively shorter, stop
operating immediately. It may result in a risk of
overheating, possible burns and even an explosion.
• Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If electrolyte gets into your
eyes, rinse them out with clear water and seek medical
attention right away. It may result in loss of your
eyesight.
• Do not short the battery cartridge:
1. Do not touch the terminals with any conductive
material.
2. Avoid storing battery cartridge in a container with
other metal objects such as nails, coins, etc.
3. Do not expose battery cartridge to water or rain. A
battery short can cause a large current flow,
overheating, possible burns and even a
breakdown.
• Do not store the jacket, battery holder and battery
cartridge in locations where the temperature may reach
or exceed 50°C (122°F).
• Do not incinerate the battery cartridge even if it is
severely damaged or is completely worn out. The
battery cartridge can explode in a fire.
• Be careful not to drop or strike battery.
• Do not use a damaged battery.
• Follow your local regulations relating to disposal of
battery.
Tips for maintaining maximum battery life
• Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
• Charge the battery cartridge with room temperature at
10°C - 40°C (50°F - 104°F).
• Let a hot battery cartridge cool down before charging it.
• Charge the battery cartridge if you do not use it for a
long period (more than six months).
• For an optimum life-time, the battery cartridge has to
be fully charged, after use.

ASSEMBLY
Installing or removing the battery
cartridge to the battery holder (Fig. 2)
CAUTION:
• Hold the battery holder and the battery cartridge
firmly when installing or removing battery
cartridge. Failure to hold the battery holder and the
battery cartridge firmly may cause them to slip off your
hands and result in damage to the battery holder and
battery cartridge and a personal injury.
To install the battery cartridge (4), align the tongue on the
battery cartridge with the groove in the battery holder and
slip it into place. Insert it all the way until it locks in place
with a little click. If you can see the red indicator (5) on the
upper side of the button, it is not locked completely.
Always install the battery cartridge fully until the red
indicator cannot be seen. If not, it may accidentally fall out
of the battery holder, causing injury to you or someone
around you.
Do not install the battery cartridge forcibly. If the cartridge
does not slide in easily, it is not being inserted correctly.
To remove the battery cartridge, slide it from the battery
holder while sliding the button (6) on the front of the
cartridge.
Installing or removing the fan unit to the
jacket (Fig. 3)
Attach the fan unit onto the jacket with closing the zipper.
And then fasten the snap button to secure it.
